With a 90-tooth gear that produces a working swing arc of just 4 degrees. the Tekton 3/8 Inch Drive x 18 Inch Quick-Release Ratchet doesn't need much room to operate. Smaller than low profile. its ultra-compact head is reduced in every dimension—height. width. and length. Sleek and comfortable. the extra long handle gives you the leverage to easily loosen stubborn nuts and bolts.
